Subject [jira] [Commented] (HADOOP-7106) Re-organize hadoop subversion layout
Date Tue, 31 May 2011 22:07:48 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13041857#comment-13041857

Jukka Zitting commented on HADOOP-7106:

As Todd already tested, the move as planned should work just fine from the perspective of
the git.apache.org mirror. The HADOOP-7106-git.sh script looks nice. Todd, I'll sync up with
you directly on how to best make this happen for git.apache.org.

I suppose we should remove the hadoop-hdfs.git and hadoop-mapreduce.git mirrors once the svn
tree has been reorganized.

Do you want to also move the resulting shared svn structure one level up from hadoop/common/{trunk,branches,tags}
to hadoop/{trunk,branches,tags} (and presumably rename the hadoop-common.git mirror to hadoop.git)?
If yes, we'll need to figure out how to best do this without breaking history in the git mirror
since our current move-svn-project.sh script can only handle cases where the entire svn structure
is moved in a single svn move (like "svn move ^/incubator/project ^/project"). One possible
solution (given help from svn admins) could be:

$ svn move ^/hadoop ^/hadoop-tmp
$ svn move ^/hadoop-tmp/common ^/hadoop
$ svn move ^/hadoop-tmp/logos ^/hadoop/logos
$ svn move ^/hadoop-tmp/nightly ^/hadoop/nightly
$ svn delete ^/hadoop-tmp

Though I'm not sure how that would look like to existing svn checkouts. Another alternative
is to simply move the trunk, branches and tags separately, and try to patch the git mirror
to properly follow such svn history. Todd, you think you could come up with a script to do
that. See the existing move-svn-project.sh script [1] for an example of the kind of history
patching we now do for more regular svn moves.
